Dear Colleagues, All of a sudden, I've begun receiving this output when reindexing my mail boxes: # /usr/local/bin/doveadm force-resync -u vas "*" doveadm(vas): Warning: Transaction log file /home/vas/Mail/sibptus/.imap/sent/dovecot.index.log was locked for 55 seconds (Mailbox was synchronized) doveadm(vas): Warning: Transaction log file /home/vas/Mail/sibptus/.imap/dss-30-06-2010/dovecot.index.log was locked for 56 seconds (Mailbox was synchronized) doveadm(vas): Warning: Transaction log file /home/vas/Mail/sibptus/.imap/dss-2014/dovecot.index.log was locked for 95 seconds (Mailbox was synchronized) doveadm(vas): Warning: Transaction log file /home/vas/Mail/sibptus/.imap/dss-20-06-2012/dovecot.index.log was locked for 72 seconds (Mailbox was synchronized) doveadm(vas): Warning: Transaction log file /home/vas/Mail/sibptus/.imap/dss-18-05-2009/dovecot.index.log was locked for 31 seconds (Mailbox was synchronized) doveadm(vas): Warning: Transaction log file /home/vas/Mail/sibptus/.imap/dss-07-12-2008/dovecot.index.log was locked for 56 seconds (Mailbox was synchronized) doveadm(vas): Warning: Transaction log file /home/vas/Mail/sibptus/.imap/dns-operations/dovecot.index.log was locked for 95 seconds (Mailbox was synchronized) And it really takes forever to finish.
